Just out of curiosity, how are the files made? Was the upload an MP3 file, an Ogg Vorbis file, both, or neither? Is there any transcoding involved in the production of the files archive.org makes available?

Thanks for the info.

In this case, the upload was in 128kbps MP3, and the OGG and the 64kbps MP3 were derived from it. You can see this if you can find the files.xml file in the song's directory:

http://audio19.archive.org/1/audio/kloss_magic/kloss_magic_files.xml

We make sure that we flag the 'original' and 'derivative' versions, so we know which one is the original - hopefully, we'll migrate that info onto the details page sometime soon, maybe with a * next to the original or something similar.

Particularly in Open-Source Audio, it'd be nice to have streamable and ZIP versions of the original uploads, but right now, if you allow the Archive to make derivatives, the streamable and ZIP versions are always the VBR and 64kbps versions - and if you upload a 128kbps MP3, you don't get VBR (because it's higher on the derivation tree, probably correctly), so your main streaming choice is, unfortunately, 64kbps MP3. That's definitely on the list to be worked out, and since we know which file is the original, we can do so safely.

s!
